Question

For an RL circuit, the phase angle is always ________

(a) Positive

(b) Negative

(c) 0

(d) 90

The question was asked in a national level competition.

My doubt stems from Resistance and Inductance in Series in chapter Single Phase Series Circuits of Basic Electrical Engineering

Answer 1

The correct option is (b) Negative

The explanation is: For a series resistance and inductance circuit the phase angle is always a negative value because the current will always lag the voltage.
